After that celebration party, Kruger was having difficulty falling asleep at night. And the reason was simple: he was too excited about the fact that LuLu is going to live with him for sure. "Are we going to make the mate contract in a short time?" Kruger couldn't stop thinking about LuLu and eventually failed to control his excitement again. So he ran out of the tribe and found a high cliff and then squatted on the cliffside to howl to the moon.
However, sadness sometimes comes after happiness.
